He made eight trips to Moscow during the 1980s, including one during which he and a leader of an American group, the Alliance of Atomic Veterans, organized a sit-in at the U.S. Embassy, demanding that the U.S. join the Soviet Union in a halt to tests of nuclear bombs.

[4][5][6][7][8] A book of Solomon's collected columns, The Habits of Highly Deceptive Media, won the 1999 George Orwell Award for Distinguished Contribution to Honesty and Clarity in Public Language.

Jonathan Kozol's introduction to the book noted that "the tradition of Upton Sinclair, Lincoln Steffens, and I. F. Stone does not get much attention these days in the mainstream press ... but that tradition is alive and well in this collection of courageously irreverent columns on the media by Norman Solomon...."[3] In 2000, Solomon teamed up with Robert Parry to write a series of investigative reports on George W. Bush's Secretary of State Colin Powell, published on Parry's website Consortium News.

[9] Solomon's book Target Iraq: What the News Media Didn't Tell You (co-authored with Reese Erlich) was published in 2003 and translated into German, Italian, Hungarian, Portuguese, and Korean.

The Los Angeles Times called the book "a must-read for those who would like greater context with their bitter morning coffee, or to arm themselves for the debates about Iraq that are still to come.

"[12] Solomon is the founder and executive director of the Institute for Public Accuracy, an organization founded in 1997 "as a national consortium of independent public-policy researchers, analysts and activists.

"[3][13] According to its web site, the mission of IPA is to increase "the reach and capacity of progressive and grassroots organizations (at no cost to them) to address public policy by getting them and their ideas into the mainstream media".

[13] As Executive Director of the Institute for Public Accuracy—which challenged Bush administration claims that Iraq possessed weapons of mass destruction—Solomon organized and led missions to Baghdad, seeking to avert the impending U.S. invasion.

"[16] Solomon emphasized his strong environmentalist background and particularly his opposition to nuclear power, which he used to differentiate himself from his primary opponent Assemblyman Jared Huffman.

[21] His overall fundraising strategy was patterned after those of Howard Dean and Barack Obama, as he sought to finance his campaign via small but continuous contributions from a large donor pool.

[23] On June 4, 2014, Solomon was among the speakers at a news conference at the National Press Club in Washington, D.C., announcing the launch of ExposeFacts.org as an ongoing project of the Institute for Public Accuracy.

In tandem with IPA, RootsAction hosted a news conference in Washington on August 14, 2014, announcing a petition with more than 100,000 signatures in support of New York Times reporter James Risen.

[25] After Biden gained the Democratic Party Presidential nomination, RootsAction launched the online "Vote Trump Out" campaign in swing states, with special attention to Arizona, Michigan and Wisconsin.

[27] It launched the campaign in New Hampshire, the first primary state, right after the fall 2022 midterm election, calling on voters to demand bold Democratic leadership.
